Kester 24-6337-8800 50 Activated Rosin Cored Wire Solder Roll, 245 No-Clean, 63/37 Alloy, 0.031 Diameter

I prefer Kester solder and have always achieved good results using Kester Solder. This size is my go to for general solder tasks and a one pound spool last a long time.

Live this stuff. Great for FPV hobbyist.

What is there to say? It’s Kester solder, it speaks for itself.

Coming off of similarly specd Radioshack branded 63/37 solder, this stuff is MUCH better. Melts faster and leaves cleaner joints even when performing repairs with old leftover solder.

Nice size for hand held soldering of wires

Ive tried other brands, Kester is the best. For almost 30 years Ive used this brand and cannot say enough good things about this solder.

Good quality solder for basic electrical project work.

Melt fast and flows nicely, I have been wondering why some of my solder flow nicely and some dont, before I place my order for my re-supply, I looked at the spools and found out I have 60/40 and 63/37 solders, the 63/37 are the one the flow nicely. This is a little more expensive but worth the money to eliminate some soldering problems.

It is decent

Highly recommended -- not the cheapest but worth the price. I wish it came in half the size / half the price option because i did not need that much.
